re: How often do you upgrade your PC

Here's the deal. You can pretty much upgrade a GPU anytime. It will be compatible with what you already have and you will see performance increase. The same cannot be said for other components. Different CPUs require different sockets. So when upgrading CPUs you should be aware of what socket your new CPU will need and purchase the corresponding motherboard. Also I if your current build DDR3 memory you will most likely need the buy ddr4 if you are upgrading.
